HENRY OPGENDRTH, OF SHEBOYGAN, WISCONSIN.

KNOCKDOWN COLLAPSIBLE SHIPPING-CRATE.

Application filed May 26, 1919.

To all whom it may concern:

Be it known that I, HENRY Orcnnon'rn, a citizen of the United States,and resident of Sheboygan, in the county of Sheboygan and State oflVisconsin, have invented certain new and useful Improvements inKnockdown Collapsible Shipping-Crates; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in collapsiblecrates formed wholly of cardboard or similar sheet material, and moreparticularly of that type adapted to contain boxes of berries or otherarticles.

It is in general the object of my invention to simplify and otherwiseimprove the structur and to increase the strength ofboxes of thischaracter when in open or set-up position, as well as to facilitate theoperation of setting up the boxes for use from the collapsed or foldedshape in which they are shipped.

With the above and other objects and advantages in view, which will beapparent as the description proceeds, my invention resides in the novelfeatures of construction, combination and arrangement of parts whichwill be hereinafter more particularly described and defined by theappended claim.

In the accompanying drawings:

Figure l is a plan view of the blank from which the outer walls of thebox are formed.

Fig. 2 is a plan view of the blank from which the remainder of the boxis formed.

Fig. 3 is a plan view of a partition blank for-the box.

Fig. 4 is an edge view of the box folded for shipping.

Fig. 5 is a perspective view of the box in partly set-up position. n

Fig. 6 is a transverse sectional view through the set-up box.

Referring now more particularly to the drawings, the outer side walls 5and the end walls 6 of the box are formed of a single elongated strip ofcardboard or similar body material bent on transverse fold lines andhaving a valance flap 7 at one end which is bent in lapped relation tothe other end and secured thereto by suitable fastening members 8 tothus provide a permanently connected foldable outer wall structure atthe time of manufacturing the box. The bottom 9, inner side Walls 10 and11 and top 12 Specification of Letters Patent.

to the length of the side walls, and the bottom 9 being disposed betweenthe inner side walls 10 and 11 while the top 12 is disposed at the outeredge of the inner wall 11. A. partition wall 13 is also provided havingits width equal substantially to the width of the end walls and havingvalance flaps 14 at its edges for securement to the wall structure.

At the time of manufacture of the box, the inner wall 10 is disposedagainst one of the outer walls 5 and these walls are secured together attheir central portions by fastening members 15 which are also passedthrough one of the flaps 1d of the partition wall 13. Thus, at the timeof manufacture, all of the parts of the box are secured together andthus held to facilitate the proper folding operations to effect theset-up or open relation of the box parts. The connected walls 5 and 10are provided with elongated sight and ventilation slots 16 which aredisposed in registry and the other outer side wall 5 is provided withother slots 17 which register with slots 18 of the side wall 11 in theset-up position of the box. The top 12 is provided on its freelongitudinal edge with flaps 19 which are adapted to engage betweencertain wall sections as will be hereinafter set forth.

In the folded shape of the box for shipping, the outer wall structure iscollapsed as shown in Fig. 4, the partition 13 lying fiat therebetween,and the bottom is folded back onto the outer face of the adjacent wall5, with the side wall 11 and top 12 folded thereonto. The thickness ofthe box when collapsed is thus only equal to the thickness of thesuperposed wall portions and a considerable economy may be effected inshipping the box.

In setting up the box for use, the top 12 and inner wall 11 are insertedwithin the outer wall structure which is opened up and the partitionwall 13 is bent to extend transversely between the side walls, fasteningmembers 20 being passed through the outer wall 5, inner wall 11 and theremaining flap of the partition wall 13 to thus firmly hold all of theparts of the box in open or set-up position, and while 1 provide aplurality of fastening members 20, it will be noted that each one of thefastening members serves the function of holding all the box parts, andthus the term smgle fastening means may be employed to desig ped in theflat state and then set up and assembled for use. It Will be noted thatin the set-up position of the box a double Wall side structure isprovided which is braced by the attaching flaps of the partition Wall.

WVhile I have SllOWll and described a preferred embodiment of myinvention, it Will be appreciated that various changes and modificationsof structure may be employed to 1ncet differing conditions of use andmanufacture Without departing in any manner from the spirit of myinvention as settorth in the appended claim.

What is claimed is:

A foldable crate structure adapted to be shipped for subsequent settingup, comprisingan elongated strip of material transversely scored toprovide foldably connected outer, side and end Walls and having its endssecured together, a second strip of material substantially equal inWidth to the length of the outer side walls and transverselyscored toprovide a top and bottom and inner side walls substantiallycorresponding in area to the area of said outer side Walls, a partitionWall having an attaching flange engaged against and extendedtransversely across the inner face ofone of the inner side Walls, and aseries of securing members passed through said attaching flange andthrough the adjacent inner and outer side Walls whereby to hold all ofsaid parts in partly assembled position and in proper relation forsubsequent setting up, said second strip of material having its portionsfoldable together exteriorly of the foldably connected outer 'alls andadapted to lie thereagainst when connected thereto by said securingmembers. 4

In testimony that I claim the foregoing I have hereunto set my hand atSheboygan. in the county of Sheboygan and State of W'isconsin.

HENRY OPGENORTH.
